Power on the server. The AC POWER lamps go on.

Confirm, by the STATUS lamp or on the POST screen, that there are no
errors related to the power supply units.

Replacing a Power Supply
IMPORTANT:
Do not remove a power supply unit operating normally.
NOTE:
If one power supply unit fails and the server contains two power supply
units in a redundant configuration, the failing power supply unit can be replaced
with the system power on. (If your server is running in the redundant power
configuration, skip Step 1 and 2 in the following procedure.)
1.
Observe the safety and ESD precautions listed under General Information
and Static Precautions at the beginning of this chapter.
2.
Perform the steps in "Preparing Your System for Upgrade" described earlier
in this chapter
3.
Locate the failing power supply unit by the AC POWER lamp on the rear of
each power supply unit. (The lamp of the failing power supply unit is
amber.)
4.
Hold and pull the handle of the failing power supply unit. The power supply
unit is unlocked.
5.
Remove the power supply unit. See Figure 4-69.
Figure 4-69. Removing a Supply
6.
If operating the server with a single power supply unit without installing a
new one, install the blank cover.
IMPORTANT:
To maintain the cooling effect in the server, install the blank
cover in the slot not containing a power supply unit.
